' SPINNING-RING.

Application filed December 16, 1915.

To all whom it may concern Be it known that 1, CHARLES D. LANNING, a citizen of the United States, and a resident of Boston, in the county of Suffolk and State of Massachusetts, have invented an Improvement in Spinning-Rings, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention relates to spinning rings and to combined spinning rings and travelers therefor.

In order that the principle thereof may be readily understood, l have disclosed certain embodiments thereof in the accompanying drawing wherein-- Figure l is a plan View of .a ring embodying my invention; Fig. 2 is a vertical, central section of the ring shown in Fig. 1; Fig. 3 is a view similar to Fig. 2, but representing a ring stamped or bent from sheet metal; and Fig. 4: represents a duplex or reversible type of ring embodying my inventicn.

From a commercial standpoint, it is important that the traveler be symmetrical or dorble-ended in form, so that the operator need not exercise special care in placing it upon the ring in a particular relation. The ring of my invention is primarily intended for use in connection with the ordinary commercial traveler, which is herein represented at 1 as of bowed form and having inturned ends 2, 3.

An important object of my invention is to provide a ring of any suitable material and either forged or stamped from sheet metal and of such a character and so proportioned that, without increasing the radial dimension of the upper flange but on the contrary employing an upper flange of the usual radial dimension and with the usral traveler, the web or body wall of the ring supporting the upper flange is so formed that the outer end 2 of the traveler, when thrown out in action by centrifugal force, does not or cannot contact with the outer surface of the web, or its contact therewith is much limited as compared with the usual conditions. It is of exceeding importance from acommercial standpoint Specification of Letters Patent.

that the length of the traveler be kept down so as to limit the weight thereof. The necessary form of the traveler is such as to engage the ring or traveler flange, and since the outer end of the traveler is thrown down by centrifugal force, it is necessary that the traveler be bowed upwardly and engage the traveler flange loosely, so that in brief it will run as free of contact as possible. The limited length of the traveler limits the width radially of the ring or traveler flange, and this limits the thickness of the web or body under the flange. Within the commercial or practical art limits, with a body or web wall having a straight or vertical outer surface, the outer portion of the traveler is thrown down by centrifugal force into contact with the web wall. Preferably employing a traveler flange of normal radial dimension and preferably employing a bowed traveler of ordinary construction, I so shape and form the inner and outer surfaces of the web or body of the ring as to provide surfaces with which the traveler will not make contact when thrown down at its outer endby centrifugal force. v

In Fig. 2, I have represented a ring produced by forging, machined down and then case-hardened and polished. The said ring is provided with an upright body 4: and an annular foot or base 5 resting upon or received by an annular ring 6, here shown as having struck up lugs 7 to embrace the base 5.

The outer wall of the web from its junction with the traveler flange 8 slopes inwardly and downwardly as represented at 9, the condition to be established being such that with the traveler in the position assumed under centrifugal force its outer por tion can be rocked upwardly and downwardly without its outer end 2 touching the portion 9 of the body or web 4. The inwardly and downwardly sloping portion 9 is carried down sufficiently far so that when the under side of the bowed portion of the traveler contacts or approaches contact with the upper portion of the traveler flange 8. the outer end of the traveler cannot contact with substantial friction with the outer surface of the body 4. Preferably also with the traveler flange and traveler of the usual Patented Feb. 29, 1916.

dimensions, it is important to form the inner surface of the web or wall 4 of the ring with an inwardly and downwardly sloping surface 10 from the point of junction with the traveler flange. This prevents contact of the inner end of the traveler 3 with the inner surface of the body or web 4' of' thering as the traveler moves into position in operation. It is not essential that both the inner and outer surfaces of the body 4 be formed or shaped as described, but preferably and to effect the best results, I do so shape or form them. I regard the shape or formation of the outer surface of thebody as of the greater importance, but it is particularly desirable that the inner surface be shaped for the purpose stated, so that in the necessarily quick starting up of the traveler after piecing up, the traveler shall not come in contact with the ring at any portion except the inner edge of the traveler flange.

The traveler flange ma be of any suitab e character, but preferably it is provided with a thin outer edge 11 of substantially the character shown in the patent to Cunnitf No. 1,161,800, the inner edge 12 of said'fiange being of markedly greater thickness and the upper surface 13 of said flange sloping downwardly and outwardly to said thin outer ed e. T he upper surface of said traveler flange may slope downin any suitable manner, but preferably either obliquely or with a concaved or recessed formation.

The desideratum in ring and traveler combinations is uniformity of friction between the ring and traveler during the spinning operation. The traveler is subjected to more or less upward and downward rocking strains due to the traverse of the ring rail, the different diameters of the bobbin onto which the yarn is laid, the uneven pull. upon the yarn and'other causes. In general, the heaviest traveler that can be used under given conditions is preferred. though sometimes the lightest permissible traveler is emplo ed, so as to obtain soft yarn. The main factor in securing uniformity of friction is freedom of the traveler in operation so far as possible from contact with the ring at any other place than the inner edge of the upper flange againstivhich the traveler is necessarily thrown by centrifugal force. As heretofore pointed out, the traveler is under best conditions of an open bow'form, the distance between the ends of the traveler being such as to lock it in enga ement with the traveler flange. The permissible weight of the traveler is most cases very small and generally speaking its length establishes its weight, most commercial travelers being of uniform cross section. Such necessary limitation of weight and length oftraveler consequently b ings about a resulting limitation in the radial dimension of the traveler flange. Such traveler flange is necessarily supported by abody or web, and the radial dimension or thickness of such body or web is sharply limited, particularly at and near its junction with the traveler flange. The necessarily upwardly bowed form of the traveleris such that as a result of its position in operationunder centrifugal force, the" outer end of the traveler is thrown downwardly, so that said traveler end tends to contact with the outer surface of the bodyofthering-,nand thereby to cause undesirable and irregular friction. Merely lengthening the; radial-dimension of. the traveler flange of the ring and movingthe bodyor web of the ring in nearerthe inner edge of the traveler flange than the-outer edge thereof does not in practice solve the problem, for, as the radial dimension of the upper flange is lengthened, the traveler must necessarily be lengthened, its general center of gravity is raised, and it consequently tends to throw into a lower position at its outer end under centrifugal force, thus causing contact between the outer end of the traveler and the outer surface of-the body or web of: the ring. I have solved these various problems and provided a ring with which, if desired, I may employ the ordinary or commercial form of traveler, and wherein the contact between the outer end of the traveler and the outer surface of the body of the ring is eliminated or reduced to a minimum,and where contact is also eliminated or substantially eliminated between the inner end of the traveler and the inner surface of the body of the ring.

As heretofore stated, the ring may be formed in any suitable manner. In Fig. 3, I have shown a ring having the characteristicsof the ring shown in Fig. 2, and of substantially the same shape, the ring, however, being stamped fro-1n sheet metal, the inner portion of the traveler flange being therefore bent upon itself. 7

Within the scope of my invention, the ring may have a single or double traveler flange. In those forms shown in Figs. 2 and 3, the ring'is provided with a single flange.

In that form of my invention shown in Fig.

body is inwardly and downwardly sloped at 17 and the lower part thereof is inwardly and inwardly sloped at 18 to a preferably median circumferential line 19, the inner surface of the upper portion of said body being inwardly and downwardly sloped. at

20, and the lower portion thereof being upwardly and inwardly sloped at 21 to a preferably median zone The ring is thereby rendered readily reversible, and in either position thereof, the inner and outer ends of the traveler are preserved from contact with the body of the ring in the spinning operation.

Obviously that form of my invention shown in Fig. 4 may be forged or formed from sheet metal and stamped into shape.

The ring of my invention is in its preferred embodiment a consequence of the requirement for small weight of the traveler,the necessary limitation of the length of the traveler as necessarily upwardly bowed tending to raise the center of gravity and tending to throw the outer end of the traveler down in operation under centrifugal force, the necessary limitation of radial dimension of the traveler flange, the necessary existence of the inner and outer parts of the traveler flange, and the necessary limitation upon the radial dimension of the body or upright portion of the ring, and particularly the radial dimension of the body at and adjacent to the under side of the traveler flange.

t will thus be evident that the various features enumerated combine in the production of a unitary result, and that whilemy invention is not in all respects limited there to, the ring herein disclosed particularly combines and cooperates with a traveler of bowed form having inwardly turned ends and of a normal length.

The thin, outer edge of the traveler flange cooperates also with the other feature of the ring and traveler in that not only is the contact between the ends of the traveler and the body of the ring eliminated or reduced to a minimum, but the contact between the outer portion of the traveler flange and the under side of the traveler is also reduced to a minimum. In view of the fact that the outer end of the traveler is maintained at all times out of or substantially out of contact with the outer wall of the body, it is easier to thread the end into the eye. This can be done by passing the end up in contact with the wall of the ring and depressing the traveler, so that the thread passes into the space between the traveler and the ring.

The preferred form of the invention and the main advantages growing out of the same may be set forth as follows: The traveler must engage the ring flange. In all commercial practice it runs above the ring flange. Due to its form, thecenter of gravity is necessarily above the plane of contact of the traveler with the flange when the traveler is pulled up against the flange, with both ends touching. Consequently when centrifugal force throws the traveler out so that its inner bend is in contact with the inner lip of the flange, the outer end of the traveler is thrown downwardly and its outer terminal swings inwardly.

No departure from a traveler made of wire of uniform cross section is desirable. Convenience requires that it be symmetrical so that no care is required as to the end which is put inside. Any weight added to the lower portion of the traveler to lower its center of gravity is objectionable. If put only on the inner end it makes an undesirable single-ended traveler. If put on both ends, or the outer end, it tends to increase the breaking strain on the traveler, resulting from centrifugal action. And fundamentally limitation of weight is essential in order that the operative friction resulting from rotation at high speed shall be kept at a minimum.

It being necessary to keep the weight of the traveler down, its length must be kept down. The result is that the radial width of the ring flange must be kept down. The result of this is that the thickness of the supporting wall under the ring flange must be kept down. The result of these conditions is that when under centrifugal force the traveler is thrown out, and its outer end is thrown downwardly and its outer terminal is swung inwardly, the outer terminal tends to contact with the outer surface of the sup porting wall under the ring flange. It is fruitless to endeavor to avoid this by increasing the radial width of the ring flange, and moving the supporting wall nearer the inner lip than the outer lip of the ring flange. For this means that the traveler has to be increased in length. Its weight is therefore increased. Due to its form, its center of gravity thus tends to be raised rather than lowered, since most of its substance is in its upper portion; and, consequently, the longer it is, the more its outer portion tends to throw downwardly under centrifugal action, and the body of the traveler tends to be thrown into contact with the upper portion of the outer edge of the ring flange. The general result is that the object of preventing friction other than between the inner bend of the traveler and the inner lip of the ring flange can be best accomplished, and, perhaps, only accomplished, under commerical limitations of weight and length of traveler, by preserving the usual dimensions and weights of traveler and ring flange, and by sloping the supporting wall inwardly and downwardly so that it lies in such position that the outer terminal of the traveler cannot contact with 1t in operation.

Having thus described one illustrative embodiment of my invention, I desire it to be understood that although specific terms are employed, they are used in a generic and descriptive sense and not for purposes of and a traveler flange, the inner wall-of the body adjacent said flange sloping inwardly and downwardly to prevent substantial contact in operation of the inner end of the traveler with the inner wall of the body.
